Original application filed May 8, 1914, Serial No. 837,135. Divided and this application filed February 19.

To all whom t may concern Be it known that I, HARVEY W. Mommy, afcitizen of the United States, and a resident of Angola, inl the county-of Steuben and State of Indiana, have made certain new and useful Improvements in Paper Holding and Feeding Means for Duplicating De vices, ofwhich the lfollowing is a speciication. 'V

My invention relates to improvements in paper holding and `feeding means for duplieating devices, and it consists in the combinations, constructions,` and arrangements herein described and claimed.

An object of my invention is to provide a device for dulilicating the work done on a typewriting machine, in which paper holders are providedwhich dispense with the necessity of using carbon copies, thereby eliminating the time necessary in inserting` and taking out carbon paper, eliminating the cost of the carbon paper and doing away with the possibility of soiling hands otthe operator by the handling'of the carbon paper.

A further 'object vof my invention is to provide a paper holder having guide means which enables the operator to tear olf sheets of predetermined size.

A further object of my invention is to provide paper feeding and holding means whereby continuous rolls may be used both on the master typewriter and on the duplicator.

Other objects and advantages will appear in the following speciiication and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this lapplication in which similar reference characters indicate like parts in the veral views in whichv s Figure 1 is a plan'view oftthe device., Fig. 2 is a front View of the device certain parts being broken away and other parts being shown in sections.

This application is a division of a prior application Serial No. 837,185 tiled May 8,

, 1914. In said prior application l have embodied claims to the general structure of the duplicating device. The claims in the present application are directed to the paper holders and feeding means of the duplicating device. In order that the action of the paper feeding means may be fully under` stood have described the structure and operation of the duplicator in the present application.

In carrying out my invention l provide a typewriter of any suitable make. In the drawings l have indicated a typewriter of the so-called basket type, but it will be understood thatthe same principle of operation might be applied to typewriters of other forms without departing from the spiritof the invention. ln Fig. .1 the keyboard ofthe main or master typewriter is shown at 1, this keyboard being provided with the 'usual keys 2. Disposed at one side ofthe master typewriter is a second typewriter. In this second typewriter the keyboard 1K has no keys 1n fact the keyboard itself might be dispensed with as far as the keys themselves are concerned except that downwardly projecting portions thereof form convenient bearings for the rock shafts which operate the type bars. For this reason l prefer to make use of machines which' have a keyboard, from-which K.fthe

keys are'removed. third typewriter havg l f 1,188,976

i `nected securely together as by means of a front plate and a metallic band 4 running rearwardly therefrom between the two typewriters. Tlie upper part of the frames of the master typewriter and the duplicator immediately adjacent is connected by means' of a bar such as that shown at 5. In order to further bind ,the two machines together so that`they may form a rigid u itary structure,,braces 6 may be secured to the bottoms ,of the frames of the two machines, these braces' being secured to a common base 7, as shown in Fig. 2. Securing devices 3", 4X, '55, and 6X similar to the securing devices 3, 4, 5 and 6 are provided for holding the adjacent duplicators together. The means for connecting the keys 2 o the master typewriter to the working parts of the duplicators is clearly shown in Fig. 8. In this ligure the keys 2 are provided with stems 8 which are pivotallyconnected at 9 to arms 10. which are rigidly secured to rock shafts 11. Each of these rock shafts 11 isV provided with the usual arm 12 whichis connected by means of a link 13 with the type bar (not shown) in the usual manner.

It will be observed, however, that each of the rock shafts 11 is provided with an L- shaped arm 14 which is connected by means of a link 15 with an arm'16 on the rock shaft, 17, of the nearestduplicator. A similar liiileJS may extend to the corresponding rock shaft of the next duplicator, so that when a key 2 is pressed on the master type- .writer the rock shaft of the master typewriter corresponding to the key and also i the rock shaft of the duplicator corresponding tothe key will be rocked. The duplicator rock-.shaft 17 has an arm 12x which is connected by a link 13x with a type bar similar'to the type bar which is operated by a pressure of the key on the master typewriter.4 Turn buckles such as that shown at 19 are provided for adjusting the effective lengths of the links 15 and 18. Each key of the master typewriter is connected withthe adjacent duplicatorfin precisely the same manner.

As will be seen from Fig; 6 the shaft 20 of the platenv 21 of the master typewriter is extended beyond the bearing 22 and beyond the stop 23 carried by the framework 24 and is provided with a gear wheel 25 which issecurely fastened to the shaft by means of a pin 26 or in any other suitable manner. The shaft 20 has a reduced portion 20 arranged to enter a socket 27 of the shaft 27 which bears the lplaten 21x of the adjacent duplicator. The shaft 27 bears a gea'r 28 having a hub 29 loosely mounted on the shaft 27 and provided with a circumferential groove 30 in which a yoke 31 is arranged to extend. This yoke is borne by a lever 32 which is pivotally mounted at 33 (see Fig. 1) on the bar 5 which connects the master typewriter with the adjacent duplicator. The hub 29 has an extension provided with slots 34 arranged to receive guide members 35 formed integrally with the shaft 27. A pin 36 passesthrough the shaft 20 and the ends of the pin are adapted to enter the slots 34 when the gear 28 is moved toward the gear 25.

Referring now toFig. 5 1`t will been seen tending arm 37, the end of which forms a bearing 38 for a shaft 39 disposed parallel with the shafts 20 and 27. The opposite end of the shaft 39 is journaled in a bearing 40` of the duplicator typewriter similar to the nearing 38 of the master typewriter. Loosely mounted onthe shaft 39 is a sleeve 41 which bears two gears 42 and 43 respectivel and an intermediate sprocket wheel 44. he gear 43 is constantly in mesh with the gear 25. The gear 28 may assume any one of three positions, to-wit; that shown in Fig. 5, in which it is in mesh with the gear 42;v an intermediate position shown in dotted lines in Fig. 5, in which it is out of mesh with the gear 42, or a position to the right in which the hub 29 is far enough over to cause the pin 36 on the shaft 2O to enter the slot 34. Now the relation of-the gears 25, 43, 42 and 28 is such that when the device is in the position shown in Fig. 5 a rotative movement of the platen shaft 2O which bears the gear 25 will cause a rotative movement of the shaft 27 of the duplicator to just half the extent of the angular rotation of: the shaft 20. In other words,'the gears25, 43, 42 and 28 are reducing gears. It will therefore be apparent that in lie spacin the movement of the platen to form a ouble space will result in a single space movement of the duplicator when the gears are in the position shown in Fig. 5.

The lever 32is provided with a locking segment 45 (see Fig. 1) and this lever may assume any one of three positions. When it is thrown 613er' to the right the gears are set as shown in F ig. 5; when it is in intermediate position, then the gear 28 is out of mesh with the gear 42, and when it is thrown over to the left the clutch member 36 enters the slot 34 of the companion clutch member, thereby connecting the two shafts 20 and 2l together so that the duplicator will now space the same as the master typewriter.

Disposed at the rear end of the typeion sel

sprocket vheel 62 having e-central flange insaeve Writer :treme is a. laterally projecting enten.

sion le lia-vin en u standin arm 47. The g e opposite end of the alined row of typewriters is provided with. a similar exten sion end arm. .The upper end of the arm is recessed to provide e retaining socket for o shaft 48 which is held in position by ineens ci a hook 49 (see Fig. 12). Disposed on the shaft is a sleeve 5G which is provided 'with ball bearings 51 at one end and with ball bearings 52 at the other end. One of the bearing members 52 is extended es shown at 53 to form a. sleeve and this sleeve is provided with an annular groove 54. |The sleeve is provided at oney end with an cnlarged portion havingy a pin 55. A spool 5o is provided'with an l.shaped slot 57 at one end (see Fig. l0) and is arranged to fit over the inner sleeve 50 and to be secured to the latter by the bayonet joint formed by the pin 55 in the slot 57. This spool is pro yided 'with a longitudinal slot 58 (see Ei 9 have described one of the paper rollers, but it will be seen from1 `ig. 10 that each machine is provided with two rollers, an upper and a lower roller. The upper rollers vere all disposed'on the shaft 4.8 while the lower rollers are disposed onA a shaft 59 which is carried b which is substantially that of the upper part 'ofthe extension 46 (see Fig. 2). This shaft 59 extendsV directly from one upright 47 to the other. Between the master typewriter and the adjacent duplicator is an llushaped frame member 60 which may be secured by means of. a laterally extending erin sgh as that shown atl in Fig. 10 to the curriege frame of either the master type- -writer or the du lieator or both. The ends ofthe ll-shaped rame member 60 are forked es shown at 60 toenter the annular grooves such las those showniat 54e and 54x in Fig. 9 thereby causing a longitudinal movement o the rollers along their respective shafts whenever the carriages are moved.

Disposed-f loosely on *theV contiguous ends of the sleeves 53 and 53? (See Fig. 9) is a ends ot the sleeves 53`and- 53x. so as to prevent longitudinal movement of the sprocketI wheel on the sleeves, hutewhich does not pre'- vent rotary movement of the sprocket with respect to the sleeves. Springs such as those shown at G3 extend laterally over each side of the sprocket. 'wheel 62 and are bentv inwardly so as to maintain a frictionel engagement-with the sleeves 53 and 532. A

sprocket chain 6d passes over the teeth of tlrf sprocket whc'el G2 and over the sprocket W5.. l #l-l 'which isA disposed intermediate of the .gears and e2. lt will be ipparent that any movement of the sprocket Wheel 44C will .be communicated to the sprocket Wheel shown in Fig. 13.

`port :i plete 67;

the arms 47 at a level- 62 and this movement in turn will be iniparted to the rollers of both the muster typewriter and the adjacent duplicatorl through the medium of the springs G3.

Secured upon the rear parts of the carriages are curved paper guides like that shown at 65 in Figs. 3 and 13. These guides ere provided with. cut-away.portions 65a :is Carried by the curved paper guide 65 on the master typewriter are arms 66 (see Figs. 3 and 13) which sup- 'lhis plate forms a support Jfor the' typewritten matter as it comes from the platen. In order to guide it in position l provide un auxiliary plate or grip of metal 68 near the bottoni of the plate 67 the lower ends oli' the pla-.tes (37 and 68 being bent in opposite,I directions, ns shown at 67E and G8 to forni 'guide ineinbers into which the edge of the paper may be placed as it comes from the platen.

The upper edge 68') of the plate GS constitutesv a knife edge or cutting edge along which the paper may be torn or cut off. At one edge of the plate G7 is a scale 69 (see Fig. 2) which is provided with perforntions 70. -Slidable ou this -scule is a laterally extending stop :ri-11171 73 may be raised so as to permit the arm 71 to be usted in various positions along the scale, and when released will cause the plunger 72 to enter one ot' the openings 7U so as to lock the stop arm 71 in adjusted positions.

F1-om the foregoing description of the viirious 'parts of the device the operations thereoqtl muy be readily understood.

The spools 5G (see Fig. 9) are designed to be supplied with paper wound therein in a roll of unbroken length. The spool containing the roll is placed on the lower shaft by removing the latterl from its bearings and slipping the spools over their respectivo sleeves such as that shown at 50 in Fig. S), and locking them in position by means of the bayonet joint, as described. understood that the paper supply rolls are placed in position for the master typewriter Well as for the duplicators. The paper is then passed over the curved guides 65 underneath the plutens of the respective typcwriters and the edge ot' the paper on the master typewritergs passed. into the guide slot between the-edges 67a und 68 of 'the plates G7 and 63 (see Fig. 13). The stop arm 71 is now -inoved into position on the plates 67 so as to indicate the proper length ot the various sheets. The carriages of the master typewriter and the duplicators be ing rigidly connected together, move in unison and they are set in position for Writing lio lt will be simultaneously with the position of the' carriege of the master typewriter. lllf it is one on the master typewriter written. with double space lines and the copies written with single space on the duplicators the lever 32 is shifted into the position shown in Fig. l. f u

Now on'operating the master typewriter in the usual manner the duplicators will make duplicate copies of the original with the exception that these copies will be single y spaced instead of double spaced, as explained. It will be observed that as the carriages of the machines travel forward they will carry with them the paper rolls so that the platens of the typewriters and the paper rolls maintain their same relative positions. The lever 74 (see Fig. 2) is the ordinary lever by means of which the platen of the master typewriter is rotated for line spacing and by which the carriages of the typewriting machines are moved when the end of a line is reached. It has been previously explained how the revolution of the shaft 2O of the master typewriter will cause the revovlution of the shaft of the duplicator adjacent to it one half the angular revolution of the shaft 20. If more than one duplicator is used the shafts of the platens of the duplicators are rigidly connected together.

When the upper end of the sheet reaches the stop arm the operator grasps the sheet and tears it olf on the knife edge or tearing edge 68". The sheets which are thus torn off are precisely of the same length.

he movement of the sprocket wheel 44 causes the revolution of the sprocket wheel 62 through the medium of the chain 64, as

heretofore described, and this causes the revolution of the upper paper rollers. The duplicate records which are being made on the platens of the duplicators are passed over the paper guides and theends of the .paper are cut and are inserted in the slots 58 of empty spools. The revolution of the spools by the frictional engagementof the springs 63 with the sleevesw53, 53x etc., causes the paper to be rolled up as fast as it is fed forwardly by the line spacing mechanism. Thus while sheets of uniform size are being torn off from the master typewriter a continuous sheet containing duplicate copies of the letters or other matter written on the separate sheets is wound on the upper rolls of the duplicators.

Instead of tearing off the sheets from the supporting means on the master typewriter the sheets may be passed directly froml the platen over the guide 65 (see Fig. 13) and may be wound on a pa er holder or spool carried by the upper ro 48 so that the matter written on the master typewriter may be kept on a roll of continuous length if desired.

In Fig. 15 -I have 'shown a modified form of means for transmitting the movement of a key of the master typewriter to that of the duplicators. In this form the key 2k of the master typewriter is at the end of a lat-- erally extending arm 11k. The arm bears on a roller 9k on an arm l0k secured to a rock shaft 15:,This rock shaft extends past the mechanism of `vthe duplicator `and is provided with an arm 16k having a rollerrlk arranged to engage a lever 18k which operates a key of the duplicator corresponding to the key 2k of the master typewriter. The other keys are connected in the same manner.

It will be seen that I have provided a device in which duplicate copies of the original may be made either having the same line spacing or line spacing one half that of the originals. Moreover these duplicate copies have the advantage of being as plainly legible as the original, since they are, in a sense, original copies themselves. Most carbon copies are not as plain as the original. The* filing them away as they would have to be were carbon copies prepared. The whole record may be lifted out from the duplicators when the roll is filled up and may be filed with very little trouble. The device is positive in its action so that no matter what is written on the master typewriter a true record is made on the duplicators. v

If it is desired to use the master typewriter by itself the lever 32 need only be shifted to the neutral position, z'. e., the central position. This disconnects the line \spacin mechanism of the duplicators from that of the master typewriter. It also disconnects the driving mechanism of the upper paper rolls of the duplicators. If for any reason it is desirable to turn the upper paper roller of either the master typewriter or the duplicators relatively to one another, this may be accomplished since the rollers are held only frictionally by the springs 63. lVhen, however, it is desired to have the rollers turned in unison the springs 63 are sufficiently strong to ca-use the' revolution of the rollers as the sprocket 62 is rotated.

This device is primarily designed to be used in connection with an electricalA or other power device for operating the kdys.

' Such devices are common and the application of the same to the keyboard of the master typewriter kis well understood. I have found in practice that a single duplicator may be very easilyoperated by the manual manipulation of the master typewriter in the ordinary manner.y
